Gy6 50cc variator recommendation anyone?

[Hotmix20021978]

I own a Taotao gy6 50cc. My belt recently snapped and I bought a new one from a dealer in my city..$32.00 ouch!? My plastic fan was destroyed and my variator and weights has wear damage. I am looking to purchase better quality replacement. Anyone have any suggestions...? I want to buy online and not wanting to replace any other parts of the transmission. Also what are the tork specks on the variator nut.... I put on the belt I got(this is my only transportation) without changing the bad parts. I think I over torked the nut causing major loss of power. PLEASE ADVISE!!
